暴露在重复subconcussive头影响(组建),特别是足球,与白质显微结构的变化和认知能力障碍。然而,足球的影响正暴露在前庭处理和平衡控制行走并没有被研究过。前庭神经电刺激(问)是一个工具,可以用来探测前庭系统在站立和行走。本研究的目的是探讨足球协会的标题与亚临床平衡赤字在散步。二十成人业余足球运动员(10个男性和10个女性,22.3±4.5年,170.5±9.8厘米,70.0±10.5公斤)沿着泡沫走道2条件下闭上眼睛:与全球之声(∼40试验),没有全球之声(∼40试验)。结果评价包括中间外侧的质量重心(COM),压力中心(COP)分离,脚位置,中间外侧的脚踝调制,髋关节内收,和脚踝推。对于每个平衡机制,全球之声的响应计算(问,意思是[没有问])。此外,参与者完成一份问卷调查,报道足球暴露在过去的一年。线性回归模型被用来确定前庭处理和平衡行走期间组建相关的风险。两脚位置(R2 = 0.324, p = 0.009)和髋关节内收(R2 = 0.183, p = 0.50)预测的组建;即,更大的接触组建与更大的脚位置和髋关节内收的反应。 However, COM-COP separation (R2 < 0.001, p = 0.927), ankle modulation (R2 = 0.037, p = 0.417), and push off (R2 < 0.001, p = 0.968) were not related to RSHI exposure. Individuals who were exposed to greater RSHI were more perturbed by vestibular stimulation during walking, suggesting that there may be vestibular dysfunction and balance impairments with frequent heading; specifically, individuals with greater exposure to RSHI responded with larger foot placement and hip adduction responses to GVS.
